Performance Analysis
The RTX 3080 demonstrates superior raw compute with 29.8 TFLOPS in FP16 and FP32, nearly doubling the Quadro RTX 8000's 16.3 TFLOPS. This advantage accelerates deep learning training epochs and inference queries for models fitting within 10 to 12 GB VRAM, reducing time-to-result in tensor core-heavy operations.
Memory capacity defines key limits: the Quadro RTX 8000's 48 GB GDDR6 enables larger batch sizes in training large language models, minimizing data loading overhead compared to the RTX 3080's 10 to 12 GB GDDR6X. However, the RTX 3080's 760 GB/s bandwidth outperforms the 672 GB/s on the Quadro, supporting faster data transfers in bandwidth-bound inference scenarios.
Power draw reflects efficiency differences, with the RTX 3080 at 320W TDP versus 260W on the Quadro RTX 8000. Ampere's architecture yields better performance per watt for modern workloads, though NVLink on the Quadro aids scaled multi-GPU training.
